This is my PGP public key. In the future, anything I write which seems especially important will be signed. This is more for signaling purposes than any fear of impersonation—signing a post is a way to strongly signal its seriousness.
That would also have the advantage of hopefully requiring different credentials to access, so it would be marginally harder to change the recorded public key while signing a forged post with it.
It still works as a signal, because (1) signing a comment requires some extra effort, and (2) it is harder to retract a comment that has been signed (since the signature remains valid proof of authorship even if the original comment is edited or deleted). A little bit of real cost and utility goes a long way.

You may want to copy this key block to a user page on the LW wiki, where it can be easily referenced in the future.

Not just harder; it would be all but impossible since the wiki keeps a hstory of all changes (unlike LW posts) and jimrandomh is not a wiki sysop.
Telling people what you’re trying to signal is a way to make them take your signaling less seriously.

But PGP’s security and quality pretty much make up for that loss in signaling seriousness, don’t you think?
Unless you’re signalling that you know about signalling including acknowledging your own signalling. :)
